-T0 ALL-WHOM IT MAY CON CERN:

Be it known that I, JOHN Si HULL, of Cincinnati, Ohio, have invented anew and useful 'Improvement in Soda-Fountains; and I do hereby declare that the following is a full and exact' description thereof, reference being had to 'the accompanying drawings, and to the letters of reference'markedthereon.

Figure 1 represents that portion of my improved fountain which is designed to be placed-upon a table or counter, and contains' the cooling-chamber. l l 'Figure 2 represents the receptacle for the soda-water with itsconn'ections with the air-pumpand with the cooler. I

The figures are taken as vertical sections.

My inventionrelates to thatl class of soda-fountains in which the water will be impregnated with soda, and and the sirupA will be-sut-ably charged with acid; and Amy invention consists in the arrangement of means of compressing aix-,in connection with' the liquid-fountain, airchambers, and tubes, whereby the' liquid will be ejected by compressed air forcediinto the water-chamber after theintroduction ofthe water, as hereinafter described. y y

The cylindrical annular space A and base Bimay be iilledwith charcoal or other suitable material, to cause the ice-chamber C to-be unaffected by a heatedv atmosphere. The faucet D serves to draw oif the water from the iccfchamber C.-y Th'e cooler E issituated near thc bottomof the'ice-chamber C', and communicates with the fountain G by means of at'ube or pipe, H,'which terminates very near the top of cooler` E. Another tube, I, connected'with the spout J, extends'through the top of the cooler, andl downwards, terminating'near the bottom ofthe cooler, as represented inkthe drawing. The fountain Gr may be placed in the cellar of a house, or inplany convenientpposition, at some'distance from the ice-chamber and cooler, and the tube connecting the two may communicate with the cooler by passing directly through the'bottom ofthe base, B, in a vertical line. The air-v pump K, constructed to charge the fountain'G withv compressed air, is secured at the side of thcfountan by means of bracket a and tube b. s is al metal valve,.which is held up in contact with itsvs'eat by the spiral spring L, but will be depressed by the action of the piston when-forcing the air into the fountain. The airwill pass throughthe horizontal `tube b when the screw-*spigot or -`tap a; is withdrawn suiiciently tonopenthe4 orifice,

.and lthe air -willpass upwards through the pipe o and enter the fountain Gr above the water-line p. After the fountain is suiciently charged with compressed air, the tap x will be screwed up, to close. the orifice and prevent leakage. i Y s A quantityof water suitably impregnated with -bicarbonate of sodais rst introduced through the open ing inV the top. of the fountain, when thel screw-plug zfwill be inserted, to make the fountain perfectly .airtight. The air-pump .will4 then-he employed to chargethe fountain, or that portion of it above the water, with compressed air, the eii'ect of which will be tocause the water to rise through pipe H into the receiver and cooler E,.wh'ich, being already filled with air in'a normal condition, will, when compressed by the introduction of the water, add its elasticity as a means of aiding the ejection of the water through the spout J when the faucet is opened for the purpose. s

It will be observed that theair-pipe oand water-pipe H both'terminate at their upper'onds above the wateril lines of the vessels with which they'communicate; also, that the lower 'ends of both the-pipes I and H communicate with their respective vessels near their bottoms. By this arrangement I insure the passage of the water from the fountain to the exit-spout J, and retainvthe` compressed airlwthin the fountain and upper portion of the cooler E.

i Having' fully described my invention, what I claim, and desire to secure by Letters Patent, is

The soda-fou'ntaiuGr, tubes H,vI, and-J, and' cooler E, combined 4and arranged for ejecting the water by compressed air forced idtozthe water-fountain, substantially as described.

In testimony whereof, I have hereunto sot my hand, this 9th day of September, 1867.

JOHNv s. HULL.
